Transponder Chips
Transponder chips are likely be found in cars that were manufactured in the last 20 years. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When activated by an electro-magnetic field the chip emits a low-level signal. This signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the computer in your vehicle system to confirm that the transponder chip that is in the key is the right one for your specific vehicle.
This prevents the vehicle from starting by hot-wiring, or by tampering. The chip inside the car key confirms that the owner is the person who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are designed like regular metal keys with an outer layer of plastic. The chip is located inside the plastic part of the keys. There are several different cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
The circuit in the induction coil emits an electrical signal when the transponder is put into an ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer inside the car is able to recognize the signal as being correct, it will disable vehicle immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as being the right one, it will prevent the engine from starting and will alert you by flashing its lights and sounding siren. This function is designed to discourage individuals from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and determined criminal could still be able to escape this security system by employing a device designed to take over the signal.
You can see that the transponder is an excellent option. Every car owner should take this into consideration when they want to safeguard their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making chirping sounds to help find a car in a parking space Key fobs today can also activate the heated steering wheel or roll down all windows with a single click. These additional features can make it difficult to find your car keys.
Key fobs utilize radio frequencies to communicate with each other and the car. The frequencies are transmitted via a small antenna that is located within the middle of the key. This communication is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.
There are several ways to program a key fob depending on your vehicle's model and make. Some cars allow you to do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a new key fob or additional one.
When you press the button on a key fob, the microchip transmits signals to the receiver in the car with which it is paired. The receiver compares the information with the 'allowed signals' stored in the key fob, and then opens or locks the car door. If the information does not match the signals, the car will not be allowed to run.
After the car has been connected to a specific fob, it will only accept signals from that device. Other fobs will not work with the car, even though they look like. This safeguards the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control over it.
Most newer car dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place with the experience to design the replacement fob is a dealer's service department. Some aftermarket fobs, usually those for older models that have less sophisticated systems can be programmed with out the need for a dealership.
